Question 572527: julie's purse contains 32 coins consisting of nickels and quarters, worth a total of $3.60. How many quarters does she have? Answer by Maths68(1474) (Show Source):
You can put this solution on YOUR website! Let
Quarters=x
Nickels=32-x
Value of a Quarter = $0.25
Value of a Nickle = $0.05
Total value of all coins = $3.6
(Value of a Quarter)(Quarters)+(Value of a Nickel)(Nickels)= Total value of all coins
0.25x+0.05(32-x)=3.6
0.25x+0.05(32-x)=3.6
0.25x+1.6-0.05x=3.6
0.25x-0.05x=3.6-1.6
0.2x=3.6-1.6
0.2x=2
0.2x/0.2=2/0.2
x=10
